4 Learning development of AVR-USB-Arduino project works by DuinoThumb V2 What s Arduino? Arduino is the standard Opensource Platform using AVR microcontroller to make the program development on microcontroller is more easier. In the past when we need to write command code on each model of microcontrollers to work, we must know that MCU* first, what are the command codes we can use? what is register? and how much is the unit? etc. When we change the model of MCU, we also have to change the command code in order to meet the values. It is quite complicated. It is different from computer that when we change the machine we can still use the same program without any problems if it just consists the same platform. This is why the open platform named Arduino has come. Also, this platform is included the basic libraries in order to make the program development is easier. Other details of Arduino are available at *MCU : Micro Controller Unit What s DuinoThumb? DuinoThumb is an AVR development board but can work with Arduino IDE which is smaller than the standard (about the thumb) but it covers the working property of Standard Arduino well. DuinoThumb does not use the standard Arduino BootLoader (serial port) but USBaspBootloader (USB port) is used to allow AVR connect to the PC without using the Serial 232 cable. In the other hand, we use USB cable in downloading the data into Flash. By this way, developing of Arduino program on DuinoThumb is easy because it is not necessary to connect further lines. Just plug DuinoThumb into the PC and install the driver, and then it is ready for programming. Moreover, DuinoThumb circuit and legs are well designed to be consistent with one of opensource project named V-USB that enables us to use DuinoThumb with other related USB works. What s V-USB? V-USB is the Library that the open source uses in AVR microcontroller emulation to deal with protocol of a USB (low speed 1.1) especially for the popular model, ATMega8/88/168 however; it can be portable to other models such as ATTiny2313 etc. There are many people using this project as a fundament to expand work development by using just only one AVR as follows - USB to Serial Converter - USB Mouse, USB Keyboard (HID) - USB BootLoader - USB Sensors - Etc. DuinoThumb circuit was designed to be used together with V-USB well. (However, some projects may need to adjust the code slightly).more details, examples of other projects and also the source code of V-USB are available at 4

5 Folders described in CD \Original_Src\ - Storage basic AVR-USB project. We can create the USB work by Just follow guidelines on the document. \Arduino\ - Just unzip Arduino IDE program (Java must be installed before), we can develop the program quickly \USBasp\ - Image and pin layout \Software\ Image viewer program and PDF file reader program (Free) Devices in DuinoThumb V2 series DuinoThumb V2 use 8 bit AVR microcontroller kind and we choose AVR ATMega 168 as a fundament. The details of this series as follows - DuinoThumb V2 board o ATmega168 AVR Features 16KByte Flash, SRAM 1KByte, EEProm 512 Byte Digital GPIO 14 bit Analog GPIO 10 bit o Port ISP - make the burning of program is easier o Voltage directly from USB (and then reduce the voltage to 3.3V) or use a jumper to connect with the voltage directly (not reduce the voltage) o Reset button o LED use in Hardware test o Crystal 12Mhz make the development can be applied with most of USB and Arduino project works - Acrylic Case - Transparent and fine case, prevent electrical short, dust and make the body strong. - CD of manual - sample basic programs 5

6 DuinoThumb V2 Schematic The DuinoThumb was designed with the main requirement to multipurpose It should be easily changed to the other project works; especially V2 can be easily repaired because there is a gap for spare parts adjustment in case of damages (Since it was designed in parallel circuit) Schematic of DuinoThumb V2 As showing in the picture, we can see that the board is really designed to use in wide range or multipurpose as described below. A - If we want to use with direct voltage (5V), we make a short at this here. Then, diodes D1, D2 may not be required. This is suitable for general AVR works. However, if we need to use 3V LED, to do the short is not necessary. B - We just designed it to spare. If we use 5V, we can connect it to R C - This is the same like Arduino and also we can give you a LED for testing D - This circuit is better than Metaboard because it also consists of ISP port (There is no ISP in the original Metaboard) so it is more comfortable if we use it with other projects. E - The schematic shows that it is designed with more than 1 set of devices and it is parallel. That is the basic equipment from the factory is SMD. However, if one day the board gets damages, we can fix it by soldering with the normal equipments with legs F - There is a Reset circuit so we can use it with USBaspLoader to make Arduino. 6

8 To develop a program by AVR and to transform AVR to be USB Devices DuinoThumb and DuinoThumb V2 are designed with port ISP, so it is easy to develop. You can select various compiler such as Basic (Bascom AVR), C/C++ (AVR-GCC) etc. - To develop the normal AVR application To develop the normal AVR program, you must have ISP AVR programming first and then plug in the cable correctly according to the DuinoThumb leg position. After that, you can make the development by using the compiler you need and compile in order to get.hex. The.hex file will be burnt into DuinoThumb through ISP port - To emulate DuinoThumb V2 to be USB Devices A principle of this programming is similar to the general development. You have to use the library of Obdev ( and follow the Obdev manual strictly. However, the most important thing is to config leg position of USB signal; D+ and D- (on file usbconfig.h) which are bit no. 2 and 4 respectively (see the schematic) To develop Arduino application and driver installation All DuinoThumb V2 boards must be installed the basic Firmware in order to support the Arduino development. Also, the Firmware is also used in Arduino test by compiling and uploading the blinkers. Therefore, once plugging in the board to USB Port of the PC or from the source to 5V, the blinker is working immediately. However, this section we will describe from burning microcontroller by Firmware in order to support Arduino development until the sample program developments by Arduino IDE to use for DuinoThumb. (In this application the Avr-Osp II is the burned program) Step burn BootLoader 8

9 1. Press Auto Detect button to find out automated MCU number. 2. Press Browse to find out the Firmware you need (should select the matching number and their own crystal) 3. Press Program to burn and then wait a moment. After finish burning, we have to set the FuseBit carefully because the MCU may get damaged if we set the FuseBit incorrectly. To set the FuseBit by AVR-Osp II is very easy, just fill in the data and then press Program How to set FuseBit 1. Select Tab Fusebit 2. Fill in the data required according to the MCU number, in this case we choose ATmega168 so we fill in the data as shown 3. Press Program and wait until complete ** For AVR ATMega8 use High Bit = C0, Low Bit = 9F ** For AVR ATMega88/168 use Ext = 00, High Bit = D6, Low Bit = DF Just this, you can use DuinoThumb in the Arduino. From now, let go to test it. Just this, you can use DuinoThumb in Arduino pattern!! Then start testing out. 9

10 Driver installation to allow the development of a USB Arduino How to setup DuinoThumb on Windows XP After the burn is complete, this device is still not activated (the PC will find the devices but does not know) because Firmware was programmed that if we would like to use the BootLoader, we have to jump the D7 leg into GND first and then reset to make the PC can find the devices. Therefore, We have to jump the D7 leg into GND first and then press reset button at the board. By this, the PC will find the file named USBasp but there is no driver so you just inform the driver address and then install driver. ** If use WinAVR version or higher, please use libusb_ ** If use the older version, please use libusb_ How to setup DuinoThumb on Linux Ubuntu The article by Acting subbieutant Arkhom Thaicharoen artchula@gmail.com Open Terminal, then connect to internet and start command line # Java Run Time Installation $ apt-get install sun-java6-jre $ apt-get install build-essential # C Language Installation on Linux $ apt-get install sdcc # AVR Library Installation $ apt-get install avr-libc # AVR -GCC Installlation $ apt-get install gcc-avr # AVRDUE Installation $ apt-get install avrdude # Remove the brltt command $ apt-get remove brltty # USB Library Installation $ apt-get install libftdi-dev # finally, go to download Arduino at $ cd # Download by type $ wget # Extract file $ tar -xvzf arduino-0016-linux.tgz Just install this, we can also develop on the real Open hardware.!!! 10

11 How to setup DuinoThumb on OSX The article by Acting subbieutant Arkhom Thaicharoen DuinoThumb can be developed on Macintosh by OSX which needs the communication port to upload data to DuinoThumb. Please follow the picture 1. Open System Preference --> Bluetooth, Press Advance (on the lower righthand) 2. Press + button on lower left-hand, there will be an additional port shows 11

12 3. Change the type of serial getting from the Modem to be RS Open Arduino IDE menu -->Tools -->Serial port, Select /dev/tty.serial-port-1 Just this, you can develop Arduino from OSX by DuinoThumb successfully. 12

13 How to setup Arduino IDE recognize DuinoThumb What we have already explained above is to burn and driver installation. However, it is not finish yet because old Arduino will not know DuinoThumb. Therefore, we have to make Arduino know DuinoThumb by the following process. 1. Open file x:\path\arduino-0015\hardware\boards.txt 2. Add below information (in the table) and save duinothumb8.name=duinothumb8 12Mhz duinothumb8.upload.protocol=usbasp duinothumb8.upload.maximum_size=7168 duinothumb8.upload.speed=19200 duinothumb8.build.mcu=atmega8 duinothumb8.build.f_cpu= l duinothumb8.build.core=arduino duinothumb168.name=duinothumb168 12Mhz duinothumb168.upload.protocol=usbasp duinothumb168.upload.maximum_size=14336 duinothumb168.upload.speed=19200 duinothumb168.build.mcu=atmega168 duinothumb168.build.f_cpu= l duinothumb168.build.core=arduino Edit the file board.txt and then save. It is complete Test by developing Arduino with real After editing the file Board.txt, then open up the Arduino IDE and wait. While waiting please check whether the DuinoThumb D7 legs are connected to GND or not. Then, press Reset at the board. After finished loading of Arduino IDE, we must choose the board that we need to develop to meet the DuinoThumb board. (See below picture) Picture showing how to select the value to match DuinoThumb board 13

14 When the program development is satisfied, then compile. After that, click Upload, the program will be sent to be programmed at DuinoThumb immediately. Guidelines for inspection and repair It could not deny that the tools or equipments would not get any damages someday. Some tools are getting damages from the factory so we have found out the problems that may occur. Also, the problems that we have found has been organized and published in order to guild the new user (because we think that most of the new user may face the problems when creating your own board) We will attempt to improve upon and you can track other new details at Problems - When plug in DuinoThumb but it is not functioning properly. Although pressing Reset, it is still not functional - Just jump D7 line into GND, the PC can find the device immediately without pressing Reset Explaination Since the function of DuinoThumb will be divided to 2 part; first is Arduino program and second is BootLoader program. Firmware will detect whether the Uploader program or regular program must be use (compare from D7 leg whether it can be put in GND or not). Sometime when we plug in the DuinoThumb into The prototype, the board is functional only in the BootLoader part because there are some error occurs with the hardware especially the R of 10 K may be getting electrical short or damages that cause the electrical current can not go to the Reset legs Inspection Simple check is to simply plug in the board DuinoThumb to USB from the legs and then jump the cable from D7 legs to GND. Then we will hear the audio signal plugs or devices found without pressing reset. That means there is the abnormal of the reset leg occurs. RESOLUTION (any way or every way). - Change the R values 10K. - Check the reset leg, it may not close properly. Problems - DuinoThumb is working slowly or almost unworkable. - Try to use different ISP but cannot found the devices Explanation If working is slow down significantly or in some cases the ISP program notice that found unknown device. Most causes of these problems are the abnormal of Crystal which will be connect to 2 Capacitors value of pf. If there is something wrong on one of these capacitors, the working property will be slower or may not work. 14

15 Inspection Try setting the time every 1 second delay and the compare with the time. If it is too delay or fast, please make a change RESOLUTION: (any way or every way). - Change C (in case of no fire or o no problems after checking). - Try checking the legs of ATMega, crystal and capacitor whether these are closed properly with the board or Microcontroller or not. Since the previous model of the boards is made as a prototype (no solder mask) in order to aviod the short. Also, they has added the Flux inside so a sticky stain may be found or may cause the board and the IC that seems "close" sometimes are not in touch with each other. If this problem is found, please use the soldering iron to touch both the board and tool for improving the movement. (it could be better) Problems - Can not use port I / O. - input / output signal is uncertain Explain: Sometime when you put an order to the input or output to go to port I/O but it still can not work as our objective or it is workable only sometimes. Inspection Try to find the reliable probe or interface I/O boards such as the Led and 7 Segment and then, try to put an order to make the light brighter by the testing program code (in CD). RESOLUTION: (any way or every way). Try checking the legs of ATMega, crystal and capacitor whether these are closed properly to the board or Microcontroller or not. The Flux stain or the lack of assembly (to enable it to work together with the signal probe) may be found because the IC that seems "close" sometimes is not in touch with the Board. If we fnd this problems, please use the soldering iron to touch both the board and tool for improving the movement. (It could be better) 15
